Application December 15, 1938, Serial No. 245,824 v1 1 j I a 2 Claims. (01. zss -se) This inventionrelates to a tank packing. An object of the inventionis to provide a tank packing or gasket formed ofrubber or similar .tresilient material and shaped to fit snugly be- 6 tween the overlapping parts of the metal plates, of which a tank is formed, and to flt closely into theangle between the vertical wall and the horizontal flange of the tank. l Another object of the invention is to provide a packing or gasket formed with angularly disposed wings one of said wings being adapted to lie between the overlapping margins of the vertical wall plates and the other wing being adapted to assume a horizontal position and to lie between the coinciding horizontal flanges of the adjacent wall plates.

It is a further object of the invention to provide a tank packing or gasket formed of resilient material and having wings united at one end and extended at approximately right angles to each other, one of saidwings being adapted to be, fitted between the overlapping margins of the vertical wall plates and having a transverse rib to fit into the angle between the vertical wall plate and the horizontal flange thereof. The other wing being adapted to be fitted between the coinciding flanges of adjacent wall platesand being provided with a transverse undercut groove to receive the opposing end margin of'the adjacent flange.

It is a further object of the invention to provide a tank packing or gasket having an intermediate thickened portion provided with an un-,

dercut transverse groove and shaped to be fitted 35 between the overlapping endsof the horizontal wall flanges,said groove being arranged to re- ,ceive the opposing end margin of the adjacent flange. 1

With the above and other objects in view the H) invention hasparticular relation to certain novel features of construction, arrangement of I parts anduse, an example ofwhich is given in this specification and illustrated in the accompanying Ydrawing, wherein: i

Figure 1 shows a fragmentary, side elevation, partly in section, of a tank wall showing the packing or gasket applied.

structed reversely to the construction illustrated g in Figure 2. a

Referring now more particularly to the drawing wherein like numerals of reference designate the" same parts in each of the figures, the numerals l, 2 designate adjacent wall plates'pfa tank whose margins overlap and are secured together by bolts as Between these overlappingmargins there is a packing strip or gasket 4 formed of resilient material and extending from top-to plates of each series also have the external top flanges as 8 extending outwardly in a horizontal direction therefrom. The flanges at the bottom of one seriesof plates coincide with the flanges at the top of the series beneath asillustrated in Figure 1 and between these coinciding flanges there is a gasket of resilient mate-. rial as indicated by the numeral 9. The end. of

the flange 6 of the plate 2 which overlaps the adjacent end of the flange 5, of the plate I, has the slightly elevated portion 6a.

It is very diflicult to packfthe joint between the overlapping ends of these flanges as well as the joint formed at the angle between the overlapping portions of the flanges and the overlap- I ping portions of the vertical, wall plates and a special form of gasket has been provided which constitutes the invention disclosed herein and which will now be described: l l

a The gasket is in the form of an L having the wings H), II. These wings taper, in thickness, toward their free ends, as shown more clearlyin Figures 3 and4. At their juncture the wing ID has a transverse, oval rib Illa. and the wing II has a transverse, thickened portion provided-with an undercut groove I la facing in a direction away from the free end of said wing I I. In assembling the wall plates of a series, during the process of erecting the tank the gasket is applied with the wing Ill fitted between the overlapping margins of the wall plates and with the rib Illa fitted into the angle between the walliplate and its corresponding horizontal flange. The remaining portion of the gasket including the wing I l is turned outwardly into a plane at right angles to the plane of the wing l and fitted between the adjacent, overlapping wall flanges. in Figure 1, the wing I0 is fitted between the overlapping margins of the plates I, 2 and the 10" bottom of the overlapping margins. 'The plates That is, as shown wing II is fitted between the overlapping flanges 6, 8 with the adjacent end of the flange fitting intothe groove Ila with the section l2, which unites the wings, lying, between the elevated portion 6d of the flange 6 and the corresponding end of the flange 5 underneath. The rib Illa thus forms a very close fit in-the angle makinga fluid tight seal at that point and the thickened portion of the wing Hi forms a very tight seal between the overlapping ends 5, 6a particularly in view of the fact that the free end of the flange 5 is I fitted closely into the transverse groove I la. As

may be noted from an inspection of Figure 2 the gasket is provided with suitable bolt holes which register with the bolt holes through the overlapping margins of the plates and flanges to-receive the securing bolts 3.

As hereinabove. stated the wings In; H taper toward their free ends. As clearlyshown in Figure 1 the complementary portions of the packing strips 4, 9 are reversely tapered so that the combined thickness of these complementary tapered portions will be thesame as the maximum thickness of the packing strips 4, 9. g

In some-situations the wing I0 is not necessary and may be either-cut off leaving only the wing l and the portion l2 or in the manufacture of the article some of the gaskets may be formed with- 1 out the wing. I0.

'incidingflanges the wing lob, Figure 5, will be At the top of each tier and underneath the coextended downwardly between the overlapping margins of adjacent wall plates instead of upwardly as shown in Figure l and the wing Hb will be extended horizontally. The gaskets used for this purpose, that is, for packing the joints at the top of each tier of staves, or wall plates, are

therefor constructed in a reverse manner with respect to the construction shown in Figure 2.

The drawing and, description disclose what is now considered to be a preferred form. of the invention by way of illustration only, while the broad principle of the invention will be defined and extending in an'gularrelation to each other, one of said wings having av transverse thickened portion on one side at the juncture of the wings and theother win-g being thickened at said juncture and having a transverse groove on the same side of the gasket as the thickened portion.
